The wiring of the RS-485 port terminals of the hybrid inverter
and the power meters terminals is illustrated in Figure 9:
•
Connect the RS-485 terminals of the power meter to
the RS-485 terminal block using a 1 mm
2
cable, which is
included in the accessory box kit mentioned in the xStorage
Home installation manual;
•
The connection to the RS-485 connection port of the hybrid
inverter should be realized via the RS-485 terminal block.
For the hybrid inverter to establish communications with the
power meters through its RS-485 port, the address of the
RS-485 port inside the power meter must be changed from its
default setting of “0075” to:
•
0001
for power meter 1;
•
0002
for power meter 2.
The process for setting the communications parameters
is the same for both power meters, with the exception of
their assigned addresses. Enter the programming mode as
described:
1. Power up the meter and irrespective of the
measurement message displayed (see display
example) keep pressing the navigation keys and
for more than three seconds until the word “Code”
appears on the LCD display.
The design of the RS-486 connector terminals is illustrated in
Figure 10.

Once the electrical installation has been carried out, the
power meter must be properly configured in order to ensure
the activation of the correct measuring mode and the correct
communications flow to the xStorage Home system, i.e.
to its hybrid inverter unit. The following illustrations explain
the communication configuration for the power meters, i.e.
for power meter 1 and power meter 2, whose purpose is
explained in the xStorage Home installation manual.
